AI-Powered supplier vetting

SummaryShandong Roadway Construction Machinery Manufacturing Co., Ltd. is a China-based limited company established in 2011, with 275 employees and 10 production lines. It reports broad customization, OEM and ODM capabilities, multiple major metalworking machines, in-stock service, and participation in the Canton Fair. Manufacturing lead time is stated as within 15 working days in both peak and off-season periods. However, the supplier has no overseas agents, branches, warehouses, or showrooms, and offers overseas services in zero countries. Important management weaknesses include no valid manufacturing-capacity contract with affiliated subcontractors, no written procedures or records for supplier assessment, corrective and preventive actions, or customer complaints, no stated quality assurance in quality control, and no continuous quantity reconciliation for production batches. Financial information identifies reporting years but provides no assessable financial results.

Supplier typeThe supplier is identified as a combined limited company named Shandong Roadway Construction Machinery Manufacturing Co., Ltd., based in Jining, Shandong, China. Its stated scope covers mechanical manufacturing for construction projects, specialized equipment manufacturing, and related technical services.

After-Sales capabilityThe supplier has no overseas agents or branches, overseas warehouse, or overseas showroom, and reports overseas service coverage in zero countries. It also lacks written procedures or records for handling customer complaints and corrective/preventive actions, indicating weak documented after-sales support capability.

Production capacityThe supplier reports 10 production lines, 275 employees, broad equipment including laser cutting, bending, punching, welding, CNC machining, milling, and pipe cutting machinery, plus in-stock capability and lead times within 15 working days in both seasons. Countervailing weaknesses are the absence of a valid manufacturing-capacity contract with affiliated subcontractors and no continuous batch quantity reconciliation or documented supplier-capability assessment.

Customization capabilityThe supplier explicitly supports customization from samples, designs, full customization, minor customization, and flexible customization. It also offers ODM services, providing direct evidence of broad customization coverage.
